TANK-WAGON FOR DELIVERING FERMENTED LIQUIDS.

SPECIFICATION formingpart of Letters Patent N o. 691,980, dated January 28, 1902.

Application led April 27,1901.

T all whom it may concern,.-

Be it known that I, VINZENZ SPIETSCHKA, a citizen of the United States, residing at Louisville, in the county of Stark and State of Ohio, have invented certain new and useful I Inprovements in Tank-VVagOns for Delivering Fermented Liquids; and I do declare that the following is a full, clear, and exact descripvtiorn of the invention, which will enable others skilled in -the art to which it appertains to make and use the same.

My invention has reference to improvements in tank Wagons for delivering fer- Inented liquids to customers from a, common tank under carbonio-acid pressure and the invention consists in a liquid-delivering tankwagon comprising a tank and wagon and associated parts constructed,v combined, and operating substantially as shown and described, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is .a side elevation of my new tank-wagon in which the wall inclosing the tank is broken away partly at one side to show internal coustructions. Fig. 2 is a'` cross-section -of the tank and wagon on a line 'corresponding substantially to A A, Fig. 1; and Fig. 3 is a crosssection of the tank above the cover Or float therein looking down from line B B, Fig. 2. Fig. 4 is a sectional elevation of the tank- Wagon looking toward the front, and Fig. 5 is a detail sectional View of the valve-chainber for the pump.

In the construction thus shown I employ a suitably-constructed vehicle as respects size and strength,provided with a platform or body 2, of any suitable style or pattern, and an upright liquid-transportation tank a, having the proportions relatively as shown, so as to carry a considerable quantity of liquid. In this instance said tank stands upright instead of lying in a horizontal plane, as tanks are ordinarily arranged vupon vehicles for carrying Water, oil, and other liquids, and this is desirable in the present instance by reason of one or more features of the invention which depend largely on an upright position of the tank to be of any practical value.

The tank a is preferably of sheetmetal, iron, or steel and internally. enameled, so as to resist chemical action. Both its ends Serial No. 57,699. (No model.)

b and c, respectively, are preferably convex orroundedoutwardlyand firmly riveted about their edges upon the flanged extremities of the side of the tank. Thesaid tank rests upon. the bottom of its inclosing casing d or upon any other suitable base or support, and the said casing or cover is preferably of wood, but

may be of any equivalent material, the idea being to make the same an inclosure which will serve the purpose of a jacket with an airspace .between it and the tank and in which cooling-coils are wound about the tank and adapted to cool the air in said space, and thus keep the contents of the tank cool also. The

said spirally-arranged cooling-coil is a'circulating coil or pipe for carbonio-acid gas from any one of the series of gas-tanks 3, 4, and 5 with which said pipe may for the time be connected.- As here shown, it is connected with tank 3; but itinay be connected with either of the reserve-tanks 4 and 5 after tank 3 is exhausted. By thus circulating gas in the cooling-coil the temperature in the air-jacket is kept down low enough to deliver cool beer from the transportion-tank in the warmest weather and climates. Circulation is in this instance promoted by a suction-pump f, having a piston operated from au eccentric e on the wagon-wheel and connected by pipe 7c with the top of the coil about tank a, Fig. 1, so that when the wagon is traveling circulation of the gas must inevitably follow and what is withdrawn is replaced by fresh gas from the acid-tank. Pump f discharges into the gas-delivery pipe h through a suitable joint at the end of the acid-tank; but the connecn@tion may be directly to said tank or to "any point in the gas output Itherefrom, and any equivalent means for operating pumpf may be adopted. Of course in the present aI'-,

rangement of pump and pipes with the acidtanks the pump will also force gas forward into the beer-tank as well as ,withdraw it therefrom, and thus establish equilibrium in the system.

The gas-delivery pipe h from the gas-tank leads to the dome of the transportion-tank and connects with the coil g, as shown here,

and is controlled bya valve 6 from without casing d, while valve -7 controls the iiow of gas to both pipes g and h. Obviously any other equivalent or suiiicient arrangement or ICO disposition of valves for these purposes may be adopted and one or more carbonic acid storage-tanks may vbeprovided. Each storage-tank has a valve 'u of its own. The said acid-storage tanks are ofvany suitable construction for sizeand strength and are always made and lined so as not to be injuriously affected bythe acid and not to impregnate the acid with anything deleterious. They may be located as here shown or in any other available position on top of or beneath the wagon-platform 2.

In the transportation-tank I employ what in a sense is a false cover, diaphragm, or separator 8, the idea being to have a movable cover or iioat over a-nd upon the liquid in the tank which will move up anddown with the liquid and rest thereon and yet serve as prac- ,tically a separator between the liquid and the acid gas above said cover, diaphragm, or separator. For brevity said part will hereinafter be referred to as a cover or float-A ing cover, and," as shown here, it is constituted of two portions comprising a substantially disk-shaped central or middle piece fm and an outer substantially ring-shaped portion n, having a rubber ring or like packing 10 in its outer edge working in contact with the inner surface of the tank. The ring ln, is preferably made of wood, while the cen- 'ter piece fm is of metal, preferably malleable iron and relatively light in weight and formed at its middle with'a long sleeve 12, adapted to slide freely on central rod 13 and long enough to hold the cover from tilting or swinging on its support. The said rod is rigidly secured at its ends in or upon the ends of the tank. The said cover rises or is raised by the iniowing liquid and always sustains. the relation of a float upon its top. Gas-pres sure from above helps to'kecp the float down in working place. The parts mand rnl are rigid with each other, and lthe outer ring or rim 'rt is provided with vone or more {loatvalves 14, normally closed from below and adapted to be opened, to run out any liquid accumulating over the cover. When the tank is emptied and is to be cleaned below the cover 8,l the said cover is raised by means of a set of cords or ropes 15, connected at its ,center and which pass out through -openings in the top of the tank and its inclosing casing. When ropes are not used, the holes-for ropes are closed with plugs to avoid escaping carbonic acid gas. After the tank has been thoroughly cleansed and closed and pumped out sufficiently to enable it to be 'lled the filling-hose 2U are screwed to pipe connection 21 for that purpose. Entrance to the tank is at its bottom by pipe connection 2l, in which there is one valve o and faucet q, as lhere shown, and the hose 20 is wound on a reel or drum 22 beneath thewagon-body. Said hose serves also for delivering or discharging the beer. When the cellar-hose is .connected up with the pipe 21 for filling, the

tank-valve o and faucet q are opened, and the liquid under pressure runs directly into the tank. If it is beer that is being drawn, the presumption is that it is in a cellar under pressure. As the tank fills the movable cover isv lifted gradually thereby to the top of the tank, and the float-valves 14, one or more in said cover, seat and close from below. When the said bottom drops down and the tank is empty, the valves 14c also drop and open of their own gravity. Having filled the tank with beer or other like beverage, carbonic acid is turned into pipes g and hby opening valves 6 and 7 and fu, when the acid or acid gas iows into both pipes and brings the requisite pressure over or upon cover 8-say five pounds or thereabout-which is constantly maintained. This being done the tank is ready for a trip and delivery to customers. A stationary thermometer 24 within the tank-cooling chamber keeps a record of the temperature about said tank, and a gage 25 tells the man on the front seat the measure of the contents, while meter 27 records the amount or quantity' of liquid delivered at any one place. All these things are convenient to the driver, who is charged with the entire supervision of the apparatus.

It is supposed that the saloon-keeper or other customer or retailer has a suitable tank or tanks into which the beer or other beverage is delivered from a wagon of this kind, and to this end the filling-hose 20' is used for mak'ing connection from the wagon-tank to the retailers tank. Thus it will be seen that no beer or other kegs as such are usedwith this system, and the receiving-tank may have any suitable capacity-say that of two or three barrels or kegs, more or less. Meter 27 shows the quantity withdrawn.

The unloading at the salobn or other point of delivery is as nected with the saloon-tank and the desired amount of beer taken out, as the meter will show, the Wagon-tank is closed and carbonicacid gas is forced through Ahose 2O to expel all traces of beer therein, when the hose are again detached and wound up on the wagonreel, and so on at each place of delivery. When an empty wagon-tank returns to the brewery, the carbonic acid is pumped out of the tank for further use, and the tank being now empty and ready for cleaning is cleaned in the manner already described. The movfollows: The hose being con able cover 8 serves especially to prevent waste of carbonic acid, as well as to preserve the beer from getting flat or even warm in its transfer from the brewery to the place of dclivery and use. and beer separated and the cover 8 always down on the body of beer, preventing frothing or foaming.

Among the advantages of this method or system of delivery is the important one of dispensing entirely with the use of becr-kegs. As there are no kegs, there areV no coopers, no wash-house man, no wash-machines, no

and obviously keeps the acid cover.

I pitch and no senese pitchrnachines, .no bungs or corks, no fastening 4of hoops, no returned loser, no stealing of kegs,l no leaks and consequent loss, and hence a greatly-reduced force of laborers and corresponding saving of expense in all these departments of the business, as Well as saving of a great amount of detail and annoyance. indeed, the system so many of the most objectionable in or about a brewing establishment and satisfactory altogether features and is so clean Vthat it practically transforms the business and totally revolutionizes the system of delivering its output to the trade. Furthermore, every customer gets actually the correct measure of his order, and bottlers cany take any quantity of beer out of the tank, while at the saine time the beer will remain under carbonio-acidpressure and be good and fresh to the last.

The oating and separating cover, as herein shown and described, is especially adapted for use wi th fermented liquids, because in .case` beer or the like be hauled in an open tank without means for keeping it quiet it will roll and dash about in such Way as toinevitably produce froth and foam, which is injurious tothe beer and materiallyimpairs its keeping quality; the cover down upon the beer across the entire tank and so connue the .beer beneath-the The cover cannot rock or roll even though-the wagonjolts or swings, and hence there is no foaming or frothing space and the injurious agitation of the beer i s-practically prevented. f
